Keyboard keys T, Y, backspace, shift and tab not working on Yoga 900

‎04-05-201801:00 PM

Good afternoon. We have a Yoga 900 and have problems with the keyboard keys T, Y, backspace, shift and tab not working. We have tried updating the keyboard driver, Windows Update, using the onscreen keyboard, and rebooting the computer - all with the same results. Does anyone have any solutions on fixing this, please? Thank you.

I am curious, does the problem occur if you boot into safe mode or login using a different user account?

If it works in Safe Mode using your normal user account, it could be some software running at startup, so try disabling startup programs and see if that fixes the problem

If it works fine under another user account, then it points to a corrupt user profile, which is a bit of pain to fix, but generally means creating a new user, and them moving your existing data from (C:\Users\<current username>, to the new user C:\Users\<new username>

If I were to guess I would say it was a corrupt user profile, so try creating a new Local user account.

Thanks for the response, JDGillis. We will try those and see if they work. It’s my daughters computer and she is currently studying abroad so it may be tomorrow before I respond given the 6 hour time difference. I’ll let you know what she finds. I appreciate your help.

Being overseas, she doesn't have access to another keyboard but did the other items you suggested. The keys still don't work in tablet mode, airplane mode and her language settings are okay. I did have her check the keys for any dirt or debris when she mentioned the first signs and there doesn't appear to be any obstructions. We are at a loss as to what would cause it and appreciate all the help.

If the physical keyboard shuts all the way off in tablet mode, then I'm at a loss beyond it being a Windows issue. If the physical keyboard still works in tablet mode, then it's debris or the ribbon cable isn't seated properly. I'm sorry I can't think of anything else.
